What happened? It became far more secure. Hashpower = network security.  They don't make it less profitable.. in fact you're so far off on your logic it's mind blowing. If that were the case then bitcoin would be worth less than a dogecoin. The most profitable long term altcoins are Scrypt, but it's not their algo which makes them profitable. The most valuable and sustainable cryptocurrency will be the one consumers use worldwide, and that may not even be Bitcoin in a few years.. who knows.

Aside from that, no cryptocurrency has inherent value, and only a few of them have somewhat tangible value. ScryptN (or ANY algo) coin value shouldn't be evaluated from the first 6 months.. not even the first year honestly. Vertcoin's hash and value is dying, just like many others.. why..? Nothing tangible. Why mine it? No consumer use. GPUC is following the same path right now. Network hash has died off severely.

Besides that, to maintain a network you need ongoing hashrate. Ongoing hashrate = more power usage. Without ASIC you limit your hashrate and increase security risks. Right now the least efficient Scrypt ASIC systems are pushing 500kh at just a few watts, and I can get them for the same price as 270 cards. Think about that for a minute.

Would you rather be mining GPUC at 500kh at say 150watts, or 5 watts? Because the latter would be giving you lower overhead and hence a more valuable turnover.

Like I said before.. hardly anyone in this thread understands the problem with GPUC, much less long term coin design and sustainability. Maybe 5 people.
